Plasmonic hot carrier-driven electrochemistry
The need for renewable energy has sparked widespread interest in photocatalysts, including systems based on plasmonic metal nanoparticles. To take advantage of these materials, a fundamental understanding of how plasmon-induced hot-carriers drive chemical reactions is needed. This work examines how …

The electrochemistry of phenothiazine derivatives
Methylene blue derivatives (MBDs) such as methylene blue (MB -), 1-methyl methylene blue (1MMB) and 1,9-dimethyl-methylene blue (DMMB) have potential use as drugs within photodynamic therapy (PDT). Knowing the redox properties of MBDs will help in understanding the way in which MBDs interact with a …

Electrochemistry and photochemistry of sulphonium salts
The cleavage in aqueous solution of the C-S+ bond in a series of related sulphonium salts having a benzyl ligand has been investigated: (i) electrochemically (ground state), (ii) photochemically (excited state). (i) Most of the sulphonium salts examined reduced in the same general manner: the …

Spectroscopy, Electrochemistry and Photochemistry of Phenylazonaphthalene Dyes
The spectroscopy, electrochemistry and photochemistry of seven 2-(4-R-phenylazo)naphthalene-4,8-disulfonate dyes (R-Span dyes), were studied to report on their structure and reactivity in water. The dyes differ in their structure by only the R substituent attached to the phenyl ring, representing a …

Synthesis, spectroscopy, and electrochemistry of hydrogenase mimics
Hydrogenases (H2ases) provide microorganisms with hydrogen to be used as fuel for processes such a methanogenesis. The reversible hydrogen evolution reaction (HER) is catalyzed by anaerobic bacteria to expel hydrogen as a byproduct of photosynthesis. Hydrogen does not accumulate in our atmosphere …
